Question

a. As a periodic signal, y(t) does not have finite energy, but
has finite power Py. Find it.

b. It is always useful to get a quick estimate of the power of a
periodic signal by finding a bound for the signal squared. Find a
bound for |y(t)|^2 and show that Py<1.

c. Use symbolic MATLAB to check the full wave rectified signal
has finite power and if that value coincides with the Py you found
above. Plot the signal and provide the script for the computation
of the power. How does it coincide with the analytical result?
